Augrented Insights

Initial analysis

The three-story, seven-unit apartment building at 1642-1646 Filbert Street in Cow Hollow, built in 1911 and currently owned by Maheshwari Irrevoc Tr, has undergone several significant maintenance and safety upgrades in recent years. Most notably, in 2023, the building received a fire alarm system upgrade costing $23,637 to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas to meet 75dB at pillow requirements. This followed a similar system modification in late 2022 that upgraded the fire panel and existing devices. Other important maintenance work has included reroofing in 2021 ($18,600), repair of dry rot on deck and rail balusters in 2018 ($10,000), and exterior staircase repairs and redesign in 2008 ($16,000).

The building has a documented history of fire safety-related issues, with violations recorded in 2005 including problems with fire proofing, combustible storage, egress obstructions, and fire escape drop ladder violations, all of which were abated by June 15, 2005. More recent fire safety incidents have been minimal, consisting mainly of false alarm activations and a single gas leak incident, none resulting in civilian injuries. The property has undergone routine housing inspections over the years, with the most recent documented inspection in 2010, and has experienced occasional maintenance issues such as water damage and inadequate ventilation in 1999. Recent 311 calls have primarily involved parking-related complaints outside the building, with no reported violations related to the building's condition or safety systems.

Risk rating

How 1642-1646 Filbert St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

23th percentile

Out of 861 buildings in this neighborhood, 663 are predicted to be safer.
